Please note that one should pay attention not to the country of the manufacturer headquarter but rather to the destination sale market country. All Nissan models for the USA market must have OBD-II support on-board (and supported by app) starting from class="searchedTermMatch">class="searchedTermMatch">1996, but the same model for EU might have no OBD-II support till 200class="searchedTermMatch">class="searchedTermMatch">1 (or 2003 for diesel) if assembled for EU market.
Please check details with the post blog What cars are supported.
Note that issues with a connection also might be due to errors with the app setting or issues with the adapter. For the troubleshooting please contact our support with mail directly from the app:
iOS version: upper right corner of Home app screen (i) - Contact us
Android version: upper right corner of Home app screen menu (|) - Info - Contact us
Thanks!
